The Fleet Lithium 51V pack is a direct match — no reprogramming, no controller upgrade, and no wiring changes. Confirm the visible controller and charger labels plus the stock motor\/controller configuration before installation. Aftermarket or modified systems should be verified separately.\u003c\/p\u003e\n\n\u003ch3\u003eWill this fit my A617.2+2G?\u003c\/h3\u003e\n\u003cp\u003eYes, on the 2026-current A617.2+2G running six 8V 150Ah lead-acid batteries on a 48V system.
